Description: This layer depicts Parcel polygons for the town of Johnston, RI. The data represented has been digitized by AppGeo from the CAD drawings provided by the Town. These CADs were georegistered and rectified to the Orthophotography by AppGeo on a block-by-block basis (to constrain any errors to be within each roadway block) while maintaining the parcel line dimension lengths in the annotation where possible. Parcel lines were digitized from this source and used to construct the ParcelPolygon layer, and coded with the Map, Block, Lot fields. Lot Number and Area annotation feature classes for this layer were created as feature-linked annotation. These polygons are contained in a seamless, town-wide parcel data geodatabase created by AppGeo that has been aligned to the 2011 RIGIS 6” Orthophotography provided by the State and linked to the Town’s CAMA database.

Description: This layer depicts the municipal boundary for the town of Johnston, RI. The data represented has been built from the parcel boundaries digitized by AppGeo from the CAD drawings provided by the Town.
